The builtin Graphviz support of CMake.
CMake can generate Graphviz files showing the dependencies between the targets in a project, as well as external libraries which are linked against.
When running CMake with the --graphviz=foo.dot option, it produces:
Those .dot files can be converted to images using the dot command from the Graphviz package:
dot -Tpng -o foo.png foo.dot
The different dependency types PUBLIC, INTERFACE and PRIVATE are represented as solid, dashed and dotted edges.
The resulting graphs can be huge. The look and content of the generated graphs can be controlled using the file CMakeGraphVizOptions.cmake. This file is first searched in CMAKE_BINARY_DIR, and then in CMAKE_SOURCE_DIR. If found, the variables set in it are used to adjust options for the generated Graphviz files.
The graph name.
The header written at the top of the Graphviz files.
The prefix for each node in the Graphviz files.
Set to FALSE to exclude executables from the generated graphs.
Set to FALSE to exclude static libraries from the generated graphs.
Set to FALSE to exclude shared libraries from the generated graphs.
Set to FALSE to exclude module libraries from the generated graphs.
Set to FALSE to exclude interface libraries from the generated graphs.
Set to FALSE to exclude object libraries from the generated graphs.
Set to FALSE to exclude unknown libraries from the generated graphs.
Set to FALSE to exclude external libraries from the generated graphs.
Set to TRUE to include custom targets in the generated graphs.
A list of regular expressions for names of targets to exclude from the generated graphs.
Set to FALSE to not generate per-target graphs foo.dot.<target>.
Set to FALSE to not generate depender graphs foo.dot.<target>.dependers.
